winflattener.exe
This is a windows command line application which takes as input any VRML'97 file, containing an arbitrary scene graph, and produces another VRML'97 file containing a single Shape node with one IndexedFaceSet node in the geometry field. It can also convert meshes to manifold meshes and a few other things within the process of flattening the scene graph. The output files should be readable by j3DPGP. If the input file points to multiple texture images, all the images are combined into a single one, and texture coordinates are recomputed. The input and output files should produce the same renderings. Run the program with no arguments to learn how to use it.

topcheck.exe
This is a windows command line application which takes as input the same files as j3DPGP, and reports numbers of singular and regular vertices, edges, and faces, connected components, and a few other things. Run the program with no arguments to learn how to use it.
